# CouchDB and IBM Cloudant

> Resources, examples, configuration and evidence for CouchDB and IBM Cloudant.

Use the `@bijection/connectors/couchdb` entrypoint to declare CouchDB and IBM Cloudant resources.

## Availability

This page describes the pinned source package. Published availability is unestablished for this artifact. [Source build and package availability](https://docs.bijection.com/client/sdk-distribution.md).

## Resources and modes

| Resource | Mode | Description |
| - | - | - |
| Database | `changes` | Changes feed |
| Database | `cloudant` | Cloudant changes feed |

Declare a resource in application code, then bind deployment-specific settings and credentials. See [typed resources](https://docs.bijection.com/integrations/resources.md), [connections](https://docs.bijection.com/integrations/connections.md) and [source inspection](https://docs.bijection.com/integrations/cli.md).

## Database

### changes: Changes feed

The following example matches configuration `standard`.

```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
import { couchdb } from "@bijection/connectors/couchdb";
import { v } from "bijection/values";

export const orders = couchdb.database.changes({
  schema: { status: v.optional(v.string()), total: v.optional(v.number()) },
});
```

> **Inferred record types**
>
> ```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
> {
>   "status": string | undefined;
>   "total": number | undefined;
>   "_id": string;
>   "_rev": string;
> }
> ```

#### Configuration: standard

Case: `couchdb/database/changes/standard`.

Connection and resource configuration are declared by this exact case.

Credential kind: `couchdb`. Keep credential material in the private credential inventory.

### cloudant: Cloudant changes feed

The following example matches configuration `standard`.

```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
import { couchdb } from "@bijection/connectors/couchdb";
import { v } from "bijection/values";

export const orders = couchdb.database.cloudant({
  schema: { status: v.optional(v.string()), total: v.optional(v.number()) },
});
```

Hosted qualification: **unestablished for this catalog configuration**. Installed connections report their own identity, authority and current status.

## Provider guidance

Compiled declaration examples and configuration details are published in the [connector reference](https://docs.bijection.com/integrations/connectors/index).

Bind the server origin (`url`) on the connection and the database name
(`database`) on the resource. Use `couchdb.database.cloudant` for IBM
Cloudant, whose welcome response names no server identity.

* **Feed.** Each page is `POST /{db}/_changes?feed=normal&since=<seq>&limit=N
  &include_docs=true&style=main_only&filter=_selector`, with a selector that
  excludes `_design/` documents. Each row is one document at its winning
  revision; `_rev` is the record version.
* **Cursor.** `last_seq` is opaque: it is not ordered, not comparable across
  cluster nodes, and grows with the shard count. The host keeps the stated
  value. A page with rows that repeats its cursor is refused.
* **Deletions.** A `deleted: true` row is a deletion. Reading from `since=0`
  lists every unpurged document, tombstones included, but no snapshot
  coverage is claimed, so absence withdraws nothing. `_purge` removes a
  document with no feed entry.
* **Replays.** After failover, shard moves or a database recreated under one
  name, CouchDB may resume shards from an earlier position: changes repeat,
  they are not skipped.
* **Writes (opt-in).** `writes: { governingRule }` adds `create`, `update`
  and `delete`, each one attempt under CouchDB's own revision precondition.
  `update` is `PUT /{db}/{docid}` with `If-Match: <_rev>` and the whole new
  document (fields it omits are removed); `delete` is `DELETE /{db}/{docid}`
  with `If-Match: <_rev>`; both use the published `_rev`, and another
  revision is a 409 refusal, never an overwrite. `create` is
  `PUT /{db}/{id}` without a revision, refused with 409 when a live document
  holds the id. 201/202 (200/202 for a deletion) is applied; 500/503 is
  unknown. A lost answer stays unknown: the server mints the new `_rev`, so a
  later read cannot attribute it. Writes require unrenamed `fields`.
* **Credentials.** `couchdb.credential(name)` or
  `couchdb.cloudantCredential(name)`: Basic, or a bearer (CouchDB JWT, a
  Cloudant IAM access token replaced manually; the IAM API-key exchange is not
  a native grant).

Not established: no request has reached CouchDB or Cloudant. Conflicting
revisions, attachments and CouchDB 1.x integer sequences are not read.
